Just a point about the stab wounds - which we have discussed some time back on the previous thread.
I did point out that those on the back and side may be shallow due to the fact that the knife had a very short blade (think Exacto knife, or even Stanley knife - box cutter for our American friends).
But the same short-bladed knife could do some nasty damage on the neck - the internal jugular vein is very superficial - it's right there, just under the skin and a very thin bit of muscle. As I pointed out earlier - it is so easily accessible, that's why we use it for venous access during anaesthesia, or in ICU, for example. And a part stab/part slash would do even more damage.
It is unusual - although certainly not improbable - for the carotid artery to be injured in direct stabbing - it tends to be much more "rubbery" due to a much thicker wall than the jugular vein, and also has the ability to "bounce" away from a penetrating wound. I've seen a patient with a chainsaw injury to the side of the neck (kickback of the saw in a professional tree-lopper) which divided almost everything on one side of the neck - EXCEPT the carotid, which was uninjured.
To cause significant injury to the carotid, there would need to be a sideways slashing component to the wound. And if there had been (I don't have access to the autopsy report - yet) then I would have expected death to be far more rapid. But poor Morgan was still alive from the time of the attack (estimated to be between 02:30 and 02:50) until the paramedics got there, when resuscitation attempts were unsuccessful.
So - and of course this is only speculation - I suspect he had major VENOUS bleeding, most likely from the internal jugular vein. And this could easily have been caused by a short-bladed knife.
So I don't draw any conclusions that the "shallow" wounds to the back and side were due to lesser force or poor stabbing technique - I would think that ALL the stab wounds would have been delivered with similar force. But the 2 or 3 to the side of the neck did the damage.
So - think length of blade, rather than force of delivery.
